Re er ing now to th drawi in detail, it will be seen that the embodiment of the inven- 5 tion which has been illustrated comprises a supto telephone motor 18 and has port which is designated generally by the reference numeral I. Mounted on the support I is a conventional telephone 2 of the hand type.

As illustrated to 'advantage'in Figure 12.0f the drawings, the;mechani sm {38 vi tzludesa comparatively :large gear 138 which ;is in mesh with the s ng w di s 4 1 t oc :mo 1 45 ;'I'he gear.39is,fixed on;a shaft QLupon which a ratchetygear -.42 also c fixed.

arms ,30 which radi swinging movement on t he shaftAl :is a leverll J vaslot1'2 provided'theretorin the 2 said lever 2|. A spring 45 returns the lever 2| to retracted position.

Also pivotally mounted on the lever 2| is an angular lever 45 which includes a finger 41 which is engageable with the pawl 44 for disengaging said pawl from the ratchet gear 42. Slidably mounted in the tubular handle portion 43 of the lever 2| is a stem 48 which is operatively connected to the lever 45 by a link 49, a slot 50 being provided in said tubular handle portion 43 to accommodate the connection between the stem 48 and the link 49. A spring is connected to the stem 58 for engaging the finger 41 with the pawl 44.

The mechanism 38 still further includes a plunger 52 which is slidably mounted in the casing 4 and which has mounted on its inner end a brake 53 which is engageable with the pallet lever 54 for stopping the clock motor l8. Slidably mounted on the plunger 52 is a collar 55 which is engageable with a pin 55 for disengaging the brake 53. A pivotally mounted lever 51 is operatively connected to the collar 55 and said lever, in turn, is o-peratively connected to the tubular handle portion 43 of the lever 2| by a link 58.

Mounted horizontally in the casing 4 is a pair of spaced, parallel channel bars 59 in which a resetting plate 55, for the time indicating ring I5 is slidably mounted. The plate 69, it will be noted, is in the form of a plate having an opening 6| therein which receives a heart shaped cam 62 which is fixed on the arms 26 of the indicating wheel |5. The plate 55 is formed to provide a pointed projection 55 which is operatively engageable with the cam 62. A rod 23, which extends slidably through the casing 4, is provided for actuating the plate 55 for resetting the time indicating ring 45. A spring 53 is provided for yieldingly maintaining the plate 60 in inoperative position.

Rotatably mounted in the upper front portion of the casing 4 is a day indicating drum 24, a month indicating drum 25, and a pair of complemental date indicating drums 26, the latter being mounted on a single shaft. The drums 24 to 25 are observed through openings provided therefor in the casing l, said drums including milled marginal flanges 21 which project through the openings to facilitate manual setting of the drums each day.

Mounted in the casing 4 is a coin box 28 which, in the embodiment shown, comprises a supporting flange 29 which rests on the inturned flange 5 of said casing 4. Coins are deposited in the box 28 by persons using the telephone through a slot which is provided for the purpose in an upper portion of the casing 4. It will thus be seen that access to the coin box 28 may be had by removing the telephone 2 from the stand I. It will further be seen that the coin box 28 may be removed, if desired, by swinging the pivoted retaining flange 1 to open position.

Journaled horizontally in the rear the base 3 are spring actuated rollers 3| and 32 upon which index and recording webs 33 and 34, respectively, are windable. The webs 33 and 34 are adapted to be withdrawn for use through an opening 35 which is provided therefor in the front of the base 3. Also operable in the opening 35 beneath the webs 33 and 34 is a plate 36 which functions as a support when writing on said webs 33 and 34. Supporting rollers 31 are provided for the plate 36 in the base 3.

portion of Briefly, the attachment functions in the following manner: The hand piece l2 of the telephone is released by disengaging the locking arm 9 therefrom after the proper key has been inserted and turned in the lock 8. The person using the telephone then pushes the stem 48 inwardly against the tension of the spring 5| for retracting the finger 41, thus permitting the pawl 41 to engage the ratchet gear 42, as shown in Figure 12 of the drawings. The tubular handle portion 43 of the lever 2| is then swung to the right in the slot 22 against the tension of the spring 45 for winding the clock motor l8. When the lever 2| is released it is returned to retracted or inoperative position by the spring 45 and the spring 5| functions to engage the finger 41 with the pawl 44 for disengaging said pawl from the ratchet gear 42, thus permitting the spring motor to unwind. Movement of the tubular portion 43 of the lever 2| to the right in the slot 22 actuates the lever 51 through the medium of the link 58 for shifting the collar 55 into engagement with the pin 56 for disengaging the brake 53 from the lever 54 of the clock motor, thus permitting said clock motor to start. The clock motor l8, as previously stated, actuates the ring |5 and the minute indicating numerals l5 thereon are observed, one at a time, as they pass the window l1. When the conversation is terminated, the slide.- ble plunger 52 is pushed inwardly for stopping the clock motor l8 and the time which the call has consumed is ascertained through the window l1 and recorded on the web 34. The rod 23 may then be pulled outwardly to reset the ring |5. As also hereinbefore set forth, the drums 24 to 26, inclusive, are manually set each day.

Any desired indicia may be recorded on the web 34 by first withdrawing the plate 36 from the hollow metallic base 3 and then pulling said web 34 outwardly thereover, said plate 38 thus functioning as a support or table for the web. The index web 33 may be used in a similar manner should it be desired to write thereon.

The clock mechanism may include an alarm to ring at intervals of three or five minutes or at any other intervals. While a spring clock motor is indicated in the drawings, an electric clock mechanism may, of course, be used if desired. The mechanism 38 and the resetting mechanism for the time indicating ring l5 are not claimed as a part of the invention.

It is believed that the many advantages of a telephone attachment constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

A telephone attachment comprising a support for the telephone, said support including a casing, horizontal rollers journaled in the casing, said casing having a window therein, a ring rotatably mounted in the casing on the rollers having minute indicating numerals on its outer periphery observable through the window, a motor mounted in the casing, a shaft rising from the motor and operatively connected to said motor, and radiating arms connecting the ring to the shaft for actuation by said shaft.
